I got these back in 2011 at the SEMA show. Sealed with the Chevrolet Holographic Sticker. These are Rare, cannot find them anywhere. I have 4 to Sell. NEVER OPENED THEM, so I cannot tell you what is inside, from the outside it looks like a comic book, not too thick. Looks as though there is a second booklet in there as well. This was a Chevrolet promo item.
